Last month, a trio of U.S. senators released their version of an Obamacare replacement bill, which they called the Patient Choice, Affordability, Responsibility, and Empowerment Act (Patient CARE Act). The legislation would initiate a host of changes to how health care is delivered in the United States . . . and that includes a wholesale rollback of Obamacare's Medicaid expansion.

According to the Center for Health and Economy,

The federal funding for the Medicaid expansion provided by the ACA is no longer available under the Patient CARE Act. Additionally, the current Medicaid funding mechanism will be replaced with capped, per-beneficiary allotments that are indexed to inflation. States will receive pass-through grants for certain high-risk populations and defined budgets for long-term and elderly care.

Translation? In many respects, Medicaid would return to its intended focus of assisting those in poverty—that is, those at and below the federal poverty level—rather than those above the poverty line. That's extraordinarily important. Obamacare's Medicaid program basically makes able-bodied, childless adults not in poverty a federally preferred class of beneficiaries, with the federal government paying a greater share of the cost for many adults above the poverty line (90/10 federal to state) than it does for all sorts of beneficiaries below it (roughly 60/40).

Are adults between 100 percent and 133 percent of the federal poverty level rich? No. Are they in poverty? Also no, by definition.

Keep in mind, too, that the Patient CARE Act is only one of many proposed overhauls of the country's health care system. All of its provisions, as well as the provisions of competing reform legislation, need to be debated on their merits in the weeks and months ahead. (We have our own ideas for key reforms of our health care system, of course.)

Make no mistake: Taxpayers have every right to be skeptical of the federal commitment to fully fund its portion of the Medicaid expansion indefinitely as the government swims in trillions of dollars of fresh debt. As the unsustainable fiscal realities of the Medicaid program and this Obamacare alternative both demonstrate, taxpayer skepticism of the expansion's future is fully warranted.
